Make sure your hubs are locked. the auto-hubs should be checked too for extreme wear.(if equipped) next look at the diff are all the gears there and not f'd up.put trans case in N and rotate front shaft, full turn with no resistance with hubs locked means diff problems. if shaft rotates in gear(any but N) and wheels off the ground, you have a Tcase problem(chain, shift linkage). so theres some things to think about.

If it has the push button 4wd selector on the dash, it is most likely the transfer case encoder motor. Not to bad to replace but you will have to remove the front driveshaft.

the connections near the front axle that activate the motor to engage the system aren't melted? That's a comon problem for that body style. If there good, sounds like it could be that motor itself. To figure out if it's you motor or transfercase, jack up the rear end, have a friend inside shift into 4 wheel drive, or try to, and put it in gear and apply some gas. If the front driveshaft is turning then it's something with the front end. If not, farther back in the system.

Dodge Dakota won't go in 4 wheel drive. could it be a fuse?


Just guessing but i am guessing the 4x4 actuator has failed. It has a plunger that engages when you select 4x4 settings. Not too expensive, worth a shot. Good luck.

Why does the 4x4 switch bink when I put it on 4 wheel dr


Yes, it is the actuator switch. It may be as simple as alignment of the actuator, or may need the wiring connector removed, cleaned and reconnected... If all that fails, you could need a new actuator. If you have 65,000+ miles, all this makes sense. If low miles, then it is likely purely an electrical issue; (such as a dirty or loose connector at the actuator).

My 4x4 fuse keeps blowing. I put in a new one, shift into 4 wheel drive and it blows. Is it a short or could my 4 wheel drive be out. It is a 1994 chevy suburan.


Try this,on the front axle there is an actuator for the 4x4,unplug it and try to engage 4x4 with it unplugged,if the fuse doesn't blow,actuator is bad.
Also look at the wires going to the actuator they get damaged from brush and things.

4/04 ford f150 4x4 front axle actuator won' t stay disengaged


Even though you checked the vacuum lines and found no leaks it does not mean there isn't a problem. The check valve in the line closest to the firewall actuator is probably your problem. Had the same issue replaced this line and solved it. The check valves in the vacuum lines are your best next guess.

97 dodge 2500 4x4 will not engage


On the axle there is a vacuum Actuator that engages a collar on the axle that engages the four wheel drive if the axel splines are worn or havent been lined up they will get burred and won't allow the collar to line up. You can remove the actuator and see the splines and determine if they need to be fixed.
